Characterizing the properties of higher frequencies for 5G applications

拟议的项目将研究无线电在杂乱的室内环境中的传播，在这些环境中，可以在2至30 GHz的频率上实施短距离5G无线通信链路。将使用软件对选定的真实世界室内环境进行建模，并且将使用软件光线跟踪来根据商定的概率密度函数来预测位于选定环境内的发送器/接收器对之间的无线电链路的窄带和宽带特性。然后将报告感兴趣的无线电信道特性的累积概率分布，其将包括：传输损耗、多径延迟窗口和RMS延迟扩展，以及主要路径信号分量以及次级路径(用于分集)和多径信号分量的接收角和偏离角。 然后，将使用矢量网络分析器来测量数据，根据该数据可以估计样本无线信道特性，以便与光线跟踪结果进行比较和校准。 最终报告将包括射线跟踪和测量结果的比较，以及在2 GHz-30 GHz范围内几个不同中心频率下的无线信道特性比较。

The proposed project will study radio propagation in cluttered indoor environments where short range 5G wireless communication links could be implemented at frequencies between 2 and 30 GHz. A selected, real-world, indoor, environment will be modelled using software, and software ray tracing will be used to predict both the narrowband and the wideband characteristics of radio links between transmitter/receiver pairs located within the selected environment in accordance with an agreed-upon probability density function. Cumulative probability distributions will then be reported for radio channel characteristics of interest, which will include: transmission loss, multipath delay window, and rms delay spread, as well as angles of reception and departure for both primary path signal components, as well as secondary path (for diversity) and multipath signal components. A vector network analyzer will then be used to measure data from which sample wireless channel characteristics can be estimated for comparison with, and calibration of, the ray tracing results. The final report will include comparisons of ray tracing & measurement results, as well as a comparison of wireless channel characteristics at several different centre frequencies within the 2 GHz-30 GHz range.
